The Eastron SDM630MV-CT belongs to the 630 series. The
meter works in combination with the current transformer (CT)
as it is shown in the picture below. The current transformer is
Eastron that belongs to the ESCT-TU16 series.

The DIN rail mount construction enables the power meter to
be installed in a compact electrical distribution box (Figure 30).

The unit can be configured to operate with the current
transformer (CT) with a 0.33V output. The secondary CT
is fixed to 0.33V, and the primary is optional. During the
installation of the power meter, no additional protective
devices are required. The meter connection terminals must
be directly connected to the L1, L2, L3 (lines) and N (neutral)
wires. The split core CT is installed on the L1, L2, L3 phases
in the same direction as the current. An auxiliary power
source that supplies the power meter must be added as it is
described in the figure 31.
